Variability in at-sea foraging behaviour of little penguins Eudyptula minor in response to finescale environmental features

Marine Ecology Progress Series, 2019
A long-standing question in ecology is how predators interact with their environment when locating patchily distributed prey. There is some evidence to suggest that marine predators use environmental features as foraging cues at meso-scales (100-1000 km);

Swimming modes affect dive durations in diving birds

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Dive duration and body mass are positively correlated across air‐breathing vertebrate species, but other factors affecting dive duration are inadequately studied. Here, we examined the effect of a previously overlooked factor, swimming mode, using phylogenetically informed statistics with data on the diving capabilities of 53 species of avian divers ...

Nest Counts of Kororā/Little Penguins on Horomaka/Banks Peninsula, New Zealand

New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
To better understand the population trends of kororā/little penguins (Eudyptula minor), the Horomaka/Banks Peninsula Kororā Survey of nesting colonies was conducted across two consecutive breeding seasons (November–January 2020/2021 and 2021/2022). Due to the number of sites and time requirements, volunteers were recruited to search 89 breeding sites ...

Factors affecting breeding success of the Flea Bay white-flippered penguin (Eudyptula minor albosignata) colony [PDF]

, 2011
The little blue penguin (Eudyptula minor) is in decline throughout much of its range in New Zealand and Australia, largely due to introduced predators, human disturbance and roadkill mortalities.

Is it possible for a Procellariiform to raise two chicks? A case of chick adoption in Southern Giant petrels Macronectes giganteus in the South Shetland Islands, Antarctica [PDF]

, 2010
We report on the adoption of a Southern Giant Petrel Macronectes giganteus chick by a breeding pair on 25 de Mayo Island (King George Island), South Shetland Islands, Antarctica.

Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

Oikos, Volume 2026, Issue 1, January 2026.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Benefits of Group Foraging Depend on Prey Type in a Small Marine Predator, the Little Penguin.

PLoS ONE, 2015
Group foraging provides predators with advantages in over-powering prey larger than themselves or in aggregating small prey for efficient exploitation. For group-living predatory species, cooperative hunting strategies provide inclusive fitness benefits.

Tere Tohorā, Karanga Tāngata: Weaving Māori Knowledge With Conventional Science to Characterise a Biodiversity Hotspot for Marine Megafauna in an Area Facing Multiple Anthropogenic Impacts

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study weaves traditional Māori knowledge and conventional scientific surveys to generate a stocktake on the biodiversity of marine megafauna in an area facing multiple anthropogenic impacts in New Zealand. Across dual knowledge systems, we show that Te Ākau/Bream Bay provides critically important habitat for a range of marine mammal and seabird ...

Early‐growth trajectories affect juvenile survival, age at first reproduction and lifetime fitness in a long‐lived seabird, the little penguin

Journal of Animal Ecology, Volume 94, Issue 11, Page 2240-2254, November 2025.
This study highlights the short‐ and long‐term effects of early development on life‐history outcomes in little penguins. By describing chick growth using 11 different parameters (including growth irregularity), weshowed that different growth trajectories lead to differences in long‐term fitness.

Balance: a neglected factor when attaching external devices to penguins [PDF]

, 2004
We observed that external attachments on penguins reduced their balance, which may be of as great concern to the individuals as the effect of increased drag. Little penguin Eudyptula minor swimming activity was observed in captivity at the Penguin Parade
